As for what those are, where to start? How about that AT&T would become the largest wireless carrier in the U.S., leapfrogging current No. 1 and bitter rival Verizon? Or that, according to AT&T, having T-Mobile's arrows in its quiver will speed 4G LTE service deployment to reach 95 percent of the U.S. population? Or that federal regulators are already sharpening their knives for a Capitol Hill showdown over the deal? Or that DT, which competes with AT&T for system integration business in several geographies, will now have an 8 percent stake in AT&T and a seat on AT&T's board? We'll be chewing over this one for months and probably years.
